Referring first more particularly to Fig. I of the drawings, a frame I 0 has appropriately journalled thereon crank shaft I l and a lower or main shaft l2, which latter may be driven from any suitable source of power in a known manner. The lay swords 13 are mounted on a sword shaft 14 and oscillate therewith. Sword shaft I4 is journalled in the frame and serves to support a part of the picking mechanism. Intermeshing gears l5 and I6 fixed on the shafts II and I2 respectively, actuate the oscillating lay beam l1 through pitmans 18, which are pivotally connected to the swords. Carried on the lay beam I1 is a reed l9 which is supported at its top by a reed cap 20, and the two shuttle boxes generally indicated at 2| and 22. Each shuttle box comprises two compartments, the construction of which will be more fully set forth hereinafter.

In general, the picking mechanism is the same on both sides of the loom; and fixed on the sword shaft l4 are supporting members 23 for the picker sticks 24. Pivoted at 25 is a treadle arm 26 carrying a shoe 21 adapted to be engaged with picker rollers 28, which are adjustably mounted (Fig. I)

on the double armed supporting member 29. The picker sticks are pivoted on short shafts 30 which are fixed on supporting members 23, and comprise a foot 31 for engagement with treadle 26 and an extension 32 whereto is attached one end of a spring 33 which is fixed at its other end to the loom frame Ill and tends to keep the picker stick in its outward position. Any conventional picker stick check means may be used, but since this forms no part of our invention, it is omitted for the sake of clarity. Spring 34 (Fig.1) fixed to the loom at one end tends to counterbalance the weight of the treadle.

Numerals 35 and 35' designate pickers which are built to conform to the shape of a cross-section of the shuttle boxes 2| and 22, and the picker stick extends upwardly through registering slots in the lay beam l1, the two shuttle compartments and the pickers.

Each shuttle box is mounted on the movable lay, and, as heretofore set forth, includes two shuttle compartments, one above the other, in which the shuttles 36 and 31 are boxed and held after pass ing through the sheds formed by the warp threads. The left-hand shuttle box 21 is of ordinary construction, but the right-hand shuttle box 22 is specially constructed in accordance with our invention, see Figs. IV-VII. Shuttle box 22 is on the replenishing side of the loom, and each of its compartments has a longitudinal slot aligned withan opening in the lay beam through which the exhausted or substantially exhausted bobbins are ejected at the time of replenishment. The rear side 38 of the shuttle box 22 comprises a fixed wall of wood or the like. This rear wall is slotted so that swell 39 pivoted on pin 40 ispositioned thereon to operate protector mechanism, check the shuttles and the like, all in a known manner. The front of the upper box compartment is divided into two parts 4| and 42, the part 4,l being pivoted at the outer extremity of the lay. The part.

42 is fixed and its inner extremity is flared to guide the shuttle into the compartment. We prefer to divide the front wall of the upper shutt e Fig. XII is a sub-assembly view, partly in seccompartment into two parts rather than .to reduce the height of a single solid wall at that portion over which the bobbin passes during the transfer operation of the lower shuttle. The front Wall of the lower compartment comprises a metal angle 43, adjustably fixed by bolts 44 to the lay beam 11. The top of the lowercompartment and the bottom of the upper compartment are one and the same and consists of a plate 45 secured by means of bolts 46 to the rear wall of the shuttle box. This plate, along with pivoted plate 41, forms the bottom of theupper shuttle compartmen't. The plate 41 pivots about'a pin 48 which passes through the bifurcated extension 49 of plate 45. Secured to plate 41 by welding or by any convenient means, such as a bracket or clip 50, is a portion of the front wall of the upper compartment; This wall is substantially co-extensive with plate 41. Inwardly and fixed to the lay beam is a bracket 5| which servesas a support for the fixed portion of the bottom and front of the upper compartment.

Clips 52, similar to thoseabove set forth, may connect the bottom and side wall portions. The front walls of both compartments have longitudinal slots which are protected by metal cam plates 53 attached by screws 54 as clearly shown in Fig. VII. The bracket 55 is bent at its top so as to serve as a rest on which the pivoted portion may slideI- A r cooperating bracket 41 is fixed to the pivoted portion and extends downwardly. The bracket 55 and adjusting screw 51 carried by bracket 41 constitute a fixed stop to limit the rearwardmovement of the yielding portion of the upper shuttle box compartment. Rearwardly, as used herein, is defined as rearwardly of the loom, This stop arrangement and the springs 64 firmly hold the pivoted portion 4| in proper alignment with the shuttles for normal weaving. The replenishing lever operating as it does to two predetermined fixed extents is adapted to cooperate with movable shuttle compartments which are alternately or successively translated by operation from any convenient moving part of the loom to position two normally superposed shuttles for. bobbin replenishment.

Master bracket 56 is secured to the forward wall of the lay beam 11 by screws 59. Ears 60 extend outwardly from the bracket to serve as a pivot bearing for the spring-controlled bell crank lever 6|, (Fig. I). A roller 62 is pivotally supported between bifurcated end portions of arm 63. Ex-

' tending at substantially right angles to arm 63 is another arm, the upper end of which passes through a perforation or hole in the yielding portion of the bottom of the upper compartment, (Figs. VI and VII). Apair of springs 64 connect laterally extending ears 65 on the bell crank lever 6| with pins 66 which are fixed to the lay beam l1. These springs are of substantial strength and hold the pivoted member 4| firmly in normal weaving position as determined by the adjustable screw 51. This arrangement causes the front wall to function during weaving in the same manner as if it were fixed but allows it to be displaced when the shuttle in the lower compartment is being refilled. Bracket 58 also carries the V-cut ,studs 200 and 2M which engage with a dagger hereinafter more fully set forth to effect movement of the replenishing lever or member.- The studs 260, 21" are adjustably' fixed and of different lengths so that they move the replenishing lever through the proper arc to refill either the upper or lower shuttle.

The replenishing magazine 61 hereinbefore mentioned is mounted on a fixed part of the loom The magazine proper 81 consists of two vertical channel members 89 and I8 which turn rearsuch as the knife rail 68 of a double plush loom.

Fixed by means of a pin 11 to the short shaft 13 is a bobbin clip supporting element I8 having a collar I9 which surrounds said shaft and which is recessed as at 88 to form a relatively firm connection between the offset member of the channel and itself. Substantially opposite the lower end of the channel bar (Figs. JHI and XIII), and on this member are pivoted two bobbin retaining elements 8|, 82 which cooperate with similar elements 83, 84 on the channels to hold the bobbin in position preparatory to transfer. These bobbin retaining elements are all pressed as by tension springs 85, 86,

which tend to hold the members in posibobbin. Stop screws 89 (Figs. XII and IHII) limit the movement of the elements BI, 82 by the springs 85, 88. The springs 81, 88 act against extensions on pivoted bell crank supports 83, 84. The cradle 98 is supported underneath the channel member by brackets 9I,

More specifically, this Bearings 98, 91 extend from along with the bearing 98, are

replenishing lever I88 comprises a yield-head or a compression hammer I8I which is controlled by spring I82 for releasably holding the head to the bobbin element support to prevent damage in the event of improper operation or jamming of the transferring mechanism. Fixed on the shaft 99 is a three-armed lever I83, two arms of which extend above the shaft and between .which .a spring is mounted to cooperate with an offset ear I84 on the loosely mounted replenishing lever proper I88 to effect'a yielding connection. A clock-like spring I85, Fig. III, has one end fixed to the knife rail 88, and the other end to a collar I86 which in turn is fixed to the shaft 99. The purpose of this arrangement is to keep the replenishing lever in retracted 'pbsition against the knife rail 68, as a stop during normal weaving. A stop ,screw I81 limits the downward movement of the-three-armed lever I83. and hence of the replenishing lever. .To avoid overthrow of the replenishing lever on its short stroke, a stop cam on an ear I88 extend ng-latand XIV). This stop cam lever I83 has a projection I84 which rides on the counterweight por- A stop I4 cooperates with the i 92 and a yielding latch 93 cooperates with. the

tion I85 of the dagger I44. When the tip of the dagger is lowered, the stop cam lever I83 is lifted and its end I86 is raised to a position higher than the end of cam I81 on the bracket supporting stop screw I81. The forward movement of the three-armed lever I83 and dagger I44, when they are moved by the V-stud 288 on the lay, causes the abutment I89 on the stop cam lever I83 to align itself with the stop screw I81, and to provide a rigid stop. Fixed on the end of the shaft 99, and on the outside of both bearings is a lever I88 comprising a collar and an arm having two special bifurcated constructed end. This end is specially. designed to cooperate with the cradle 98 (Fig. X) which successively positions the bobbins in the magazine channels so that they may be inserted substantially vertically into the exhausted shuttles. The cradle proper comprises a shaft I89 having two supporting members II8 for the bobbin directly above the bobbin in transfer position.- On the end of the shaft I89 there is fixed a sector 94 (Fig. XIII) having circumferentially-spaced indentations, and an arm III which cooperates with the bifurcated arm I88, on the replenishing lever shaft 99. The indentations cooperate with the beforementioned spring controlled yielding latch 93 to hold the bobbin porting members. The bifurcated lever I88, being fixed to the shaft 99, is moved a greater or less extent depending on which shuttle is to be refilled. When the replenishing lever I88 gets its long or short stroke to refill an exhausted shuttle,

the prong I I2 moves completely past the arm I I I, and accordingly moves it and the cradle .98 to the same extent regardless of whether or not a shuttle in the upper or lower box is being refilled.

The prong M3 on its return stroke resets the magazine cradle and allows it to support a new bobbin which has been advanced by gravity. The

supporting members III] of the cradle 98 are so proportioned in respect to the size of the bobbin heads that the entire supply is not forced backwardly during the resetting action, the bobbin being supported by the members II8 before the first bobbin of the group .is forwarded 'to the lower end of the magazine. 8

To the outer end of the weft replenishing lever shaft 99 (Fig. IV) is affixed an arm II4 having a stud I I5 at its upper end capable of turning in the flattened and bored end of a link H8. Small collars III and H8 are fixed on the link. and the collar II'I serves as a shoulder for a spring II9 which surrounds said link and presses through a semi-ball I28 at its other end against a knife arm I2I pivoted on a pin I22. A stop bracket I23 secured by bolts I24, has an upstanding projection I25 which limits the forward movement of the knife lever I2I to a definite position regardless of whether the*replenishing lever is moved to replenish a'shuttle in either the upper or the lower compartment. 8

The knives I26 (Fig. V) are of and are pivoted about fixed pins the shear type I21 on the flat Compression springs I29 tend to keep the shear blades open and springs I29 tend to keep the cutting surfaces in shearing contact. Forwardly (of the loom) the'shear blades I26 baveoffset extensions I38, and the compression springs I29 are positioned to keep the shears open to the limit allowed. by stops I3I until theyare closed by the camming action of the flare-on plate 53, throughwhich they are extended to cut the weft of the exhausted bobbin near the shuttle eye at the time of replenishment. The shuttles 36, 31 have slots which align with the slots in plate 53 when the shuttle is properly boxed.

Replenishing lever I (Fig. III) carries an intermediate stud I32 on which cam lever I33 is pivotally mounted with the cam portion I34 facing upwardly, and the projection I35 extends through a slot in the knife 68. Accordingly, when the replenishing lever I00 is depressed, the cam lever I33 moves with it and engages a roller I36 at one end of a two-armed hook lever I31 which is pivoted on a stud I31 upstanding from the knife rail 68. The motion of lever I31 imparts a straight rearward thrust to hooks I38,

I39 which are fixed toa carriage I40 (Fig. III). The arm of the lever I31 opposite to that on which the roller is mounted is forked and engages a stud !4I on the carriage I40. A T-shaped groove in member I42 fixed to the knife rail 68 guides the carriage. The hooks I38, I39 engage the threads at a point between the selvage and the inner ends of the front walls of the shuttle compartments on the replenishing side. A selvage cleaner generallyindicated at I43 (Fig. III) removes the end of the weft from the exhausted bobbin and the end from the first pick from the selvage of the woven material. This may be operated from the oscillating lay.

Fig. I shows the replenishing lever shaft 99in substantially the same horizontal plane as the front of the bottom of the top shuttle box com-' partment. This has been found to be even more desirable than position ng it above thisplane in which position the hammer portion I M of the replenishing lever I00 would be moving in the same direction, i. e., forwardly during a portion of the replenishing operation.

At the lower end of the three-armed lever I03, which controls the replenishing lever I00, there is mounted (Fig. IX) a counter-weighted and spring-controlled dagger I44. On said dagger, and extending laterally thereof, are studs I45, I46 which support rollers I41, I48. The spring control comprises a bracket I49 fixed to the under surfaceof the knife rail. A central vertical portion of the bracket has a pair of offset. ears at each side thereof cooperating with rod-like elements I50, II around which compression springs I52 are mounted. Rod I50 is bent at the top, and tends to prevent the dagger I44 from moving upwardly, whereas rod I5I supports the dagger and tends to prevent it from moving downwardly, thus establishing effective contact during replenishment. The dagger arm I44 is thus held in neutral position intermediate the V-cut studs 200 and 20I when the lay is forward during normal weaving.

The dagger I44 is moved at the time of substantial exhaustion of the weft. bobbin to effect replenishment. Stop cam lever I53 is freely pivoted on a pin I53 in bracket I54 which is secured to the under side of the knife rail 68. The movement of cam lever I53 is limited by the base of the bracket and by the adjustable screw I55 (Fig. I) A laterally extending element I56 is fixed on the stop cam lever I53 and projects over dagger I44 for engagement'therewith when the lower shuttle is being refilled, the action being that the dagger lifts the cam lever up against stop screw I55 thus allowing roller 62 on the arm 6| tobe forced downwardly. as the lay advances, to effect yielding of the front wall of the upper compartment A bracket I59 fixed onthe under side'of the I knife rail extends downwardly and serves as a bearing for short shaft I60 and stud I 6| and, together with another bracket I62, as a bearing for the main timing shaft I63 which extends longitudinally of the knife rail 68. Fixed on shaft IE3 is a sprocket wheel I64 driven. by link chain.

I51 (Fig. I). Loosely mounted on shaft I63 for sliding movement but keyed against angular movement is a sleeve'I65 comprising a flange I66 and projecting ears I61 through which a pin I68 is positioned as a pivot about which the head I69 of the dagger rotor I may turn to a limited extent. The shaft I63 makes a complete revolution for every 16 crossings of each shuttle or picks. The distance between rollers I41 and I48 on the dagger represents predetermined and is an odd number of picks when measured by. the number of picks it takes the rotor to pass from one to the other. In the present instance the rollers I41, I48 on the dagger I44 are spaced so that they will co-act with the rotor head I69 on the first and fourth pick of the replenishing cycle. The rotor I10 and timing chain I18 are initially set to effect replenishment at substantial exhaustion. of the first pair of bobbins. No further setting is necessary. The rotor head I69 is capable of yielding in one direction, and is normally held against a stop I61 (Fig. VIII) by means of tension spring I1I (Fig. IX) connected at opposite ends to offset ears respectively on the rotor head I69 and the collar I65. 7

Short shaft I60 'as clearly shown in Fig. VIII carries the fixed sprocket I12 and disc I13. Pivotally mounted for horizontal swinging movement on the bearing hub for the shaft I60 (Fig. VIII) is a two-armed lever I14, one arm of whichefiects I) is aflixed to one end of shaft I63 and accordingly advances the disc- I13 one tooth and the chain one link for every 16 picks. A springpulled lever I92 carries a roller I93 and holds the disc I13 firmly in tooth-meshed position, but allows manual movement if it is desired to set or alter the time of replenishing. v

I Weft replenishing actuating ears are positioned on the chain I18 at intervals corresponding to the length of weft on a full bobbin.,

Operation Preparatory to weaving on a multi-shed loom with two shuttles carrying bobbins with measured wefts of a known length as herein set forth, the timing chain I18 is placed about sprockets I 19 and I80 so that when a set of ears thereon reach the roller I18 to ihitiate replenishment, the measured bobbins will be substantially exhausted and the rotor head I69 will be positioned ahead of rollers I41 and I48 on the dagger I44. The chain, being advanced every 16 picks, :will on bell crankJiI (Fig. I) to passunder and raise a given pick after engaging the roller cause two'- armed lever I14 to shift the sleeve I and hence.

.v-cut stud 200. The forwardly moving lay will carry the dagger forwardly with it and turn three-armed lever I03 about its shaft 99 against the action of the clock-like spring. This motion of the three-armed lever causes the replenishing lever to descend and engage a full bobbin in the magazine 61, such engagement taking place bemovement of both the lay and the replenishing lever causes the new bobbin to be inserted-in the upper shuttle and the exhausted bobbin to be concurrently ejected therefrom. The downward motion of replenishing lever I00 and the concurrent rotation of the carriage lever I31 causes the hooks I38, I39 on the carriage to be moved inwardly and the upper hook to. engage the weft of the-upper shuttle. Simultaneously, shaft 99 and link I I6 moves the shears inward where they are cammed to closed position as they enter further into plate 53, and cut the weft from the old bobbin as the lay moves forwardly. The V-stud 200 moves away from the dagger and allows shaft 99 andreplenishing lever to be returned to their original positions by the clock spring. The hooks are withdrawn, carrying with them the cut end of the exhausted bobbin, and. the cutters are returned to their original posi tion. The rearward motion of the lay permits the weft caught on the hook, to be completely withdrawn from the shuttle box.

Simultaneously withactuation of the replenishing lever I00, the link I08 moves ,downwardly and turns the notched sector 94 as clearly shown in Figs. XII and XIII to advance a bobbin in the magazine. The reverse movement of shaft 99 moves sector 94 back to its original position. In the meantime, the exhausted bobbin has passed down through the lay'beam freefrom the loom.

On the fourth pick, the rotor head engages roller I49 and moves the daggerup into the path of V-stud MI. The action is similar to that above described except that stud ZIII moves the dagger a greater distance to replenish'the lower shuttle. Elevation of dagger I44 raises cam lever I53 by means of the laterally extended element I56 on the latter and allows the roller 62 of the said cam lever up against adjustable screw I55. Continued inward motion of the lay causes the bellcrank to pivot about its, fulcrum and move.

the yielding portion 4| of the upper shuttle box compartment as the hammer on the replenishing lever moves deep in the shuttle box to replenish the lower shuttle. The V-cut stud ZOI, projecting as it does ahead of V-cut stud ZIIILengages fore the lay is on front dead center. Continued course, occurs before the rotor has again engaged a roller on the dagger. The temple clears the selvage of the cut end of the old bobbin and the end of the first pick of the new bobbin.

Having thus described our invention, we claim:

There is an actual movement of the bobbin'away from the replenishing lever head. The operation of the shears, hooks. and the advancement of the bobbins is similar to their first described motions except that this time the lowerhook functions I39 to withdraw'the cut weft, and the stop I25 has limited the inward motion of theshears.
